Futuristic design from AVI Astroport. Avast! I made t' followin' modifications t' me clone. T' phaser tube are 4.5" plastic addin' machine rolls. Well, blow me down! BT is 1.25"x36" gift-wrap tube that I salvaged from goin' in trash. Nose and coupler from scrap balsa wood white glued into a block then cut and sanded t' shape. Avast! I cut a 4" section from BT t' glue betwixt nose cone and coupler. I also changed t' MM from 18mm t' 24mm. T' last change was t' go with a single 20" parachute instead o' t' twin 14" 'chutes. Other wise followed plans.     http://www.oldrocketplans.com/avi/aviAX-1/aviAX-1.htm
